CONVECTOR-RADITOR Filed Nov. 17, 1967 mentor y United States atent O 44/ 67 Int. Cl. F2411 9/04, 3/10; F28f 1/18 U.S. Cl. 165-55 2 Claims ABSTRACT OF THE DISCLOSURE A convector-radiator substantially inthe form of a bottomless metallic cabinet enclosing a plurality of parallel baille metallic elements mounted spaced from one another on a pipe section crossing the same. The said cabinet is integral with said batlie elements and has its upper front portion cut-away thus permitting a free air liow therethrough.

Background of the invention This invention relates to a convector-radiator for water circulation heating plants and which may be combined with other similar radiators to form a heating unit.

One of the disadvantages of known hot-water heating plant radiators is that they are extremely unwieldy and cumbersome and are consequently invariably subject to installation problems.

It is known that this disadvantage is not obviated by the use of convectors since, even if the heating element is of limited encumberance, it is necessary to enclose the heating element in a cabinet whose dimensions do not greatly differ from those of the smallest radiators.

This problem of unwieldiness is of considerable topical importance since modern flats and houses are provided with an extremely limited amount of free space.

An object of the invention is that of providing a convector-radiator for water circulation heating plants which may be coupled with other similar radiators to form heating units and which has a structure which is of limited eucumbrance, both in width and depth, so that said radiator may be readily installed in any given space without the use of cabinet units or the like.

Another object of the invention is that of providing a convector-radiator which, besides being of limited encumb'rance, has both a large radiant surface and a large heating surface for the air circulating within the radiator.

A further object of the invention is that of providing a convector-radiator which, due to its structure, has a high efliciency both as a radiator and as a convector since both the heating surface for the internally circulating air and the radiating surface have an extremely small difference of temperature from one point to another.

A further object of the invention is that of providing a convector-radiator whose structure is such as to be readily manufacturable.

Summary of the invention These and other objects which will appear more clearly hereinafter are achieved by a convector-radiator according to the invention which is characterized in that it iS formed of a metallic monobloc body which comprises an outer box member which is provided at its upper and lower ends with at least one aperture which extends along the entire length of said box member, said box being internally provided with a plurality of baffles arranged parallelly to the sides of said box member, said baffles being connected to the front and rear walls of said box and to a tubular member which extends from one of said sides to the other, the ends ot said tubular member being provided 3,470,947 Patented Oct. 7, 1969 p y ICC with coupling means adapted to enable the coupling of said radiator with other similar radiators.

Brief description of the drawings Further characteristics and advantages, which will appear more clearly from the following detailed description, are achieved by a convector-radiator according to the invention, illustrated by way of example in the accompanying drawing in which the single figure shows a perspective and partially exploded view of a convector-radiator according to the invention.

Description of the preferred embodiments With reference to said figure, two convectorradiators 1 and 2 are coupled to form a heating unit. Each of said radiators (specific reference is made to the radiator 1) is formed of a metallic monobloc body which is preferably produced by casting, or rather diecasting. Said monobloc body comprises a box-like cover which is generally indicated at 3.

Said cover 3 has a pair of lateral sides 4 which are eS- sentially rectangular without the front corner and which consequently have an inclined edge 5. Said edges 5 are not perfectly rectilinear but are provided with a slight concavity. Said sides 4 are interconnected by a front wall 6 the upper end of which extends to the level of the lower end of said concavity, a top lid or top wall 7 which has a width equal to the horizontal section of the upper ends of said sides 4, and a rear wall 8 whose height is less than that of said front wall 6.

From what has been described it should be clear that the lower end of said box-like cover 3 has an aperture, indicated by reference numeral 9 which lies in a horizontal plane and extends through all the cross-section of said cover. The upper end of said cover has an aperture 10 which is inclined to the horizontal and which is contained between the front wall 6, the lid 7 and the two sides 4.

It should also be clear that @the rear of said cover has an aperture, said latter aperture being indicated by reference numeral 11. However, as will appear more clearly hereinafter, said aperture 11 is non-functional and, according to whether or not the radiator is placed against a structural wall, said ape-rture 11 is either covered by said structural wall or by a plate member which is secured to said radiator by means of screws 13 as will be seen hereinafter.

Said box-like cover 3 is internally provided with a plurality of baflle fins 14 which are evenly spaced, arranged p'zlrallelly to said sides 4 and have the same shape as said si es.

On two of said batiles, indicated by reference numeral 15, a pair of projections is provided, the single projection visible in the figure being indicated by reference numeral 16. Said projections are provided with thread holes to receive said screws 13 which secure the plate-like member 12. Each of said convector-radiators which as said previously, is monobloc is completed by a tubular member 18 which extends from one to the other of said sides 4. Said tubular member 18 has an external cross section (evidently excluding the points of connection with said bales 14) which is circular for three quarters, the remaining quarter being formed of two rectilinear sections which are horizontal and vertical respectively.

Said tubular member 18 projects slightly from either side of the walls 4 and on such projecting portions are provided connection members which enable the ready coupling of the radiator to further similar units. In the figure the male part of such connection members is visible, said male part being formed of a pair of lugs 19 which are adapted to be inserted into conjugate slots provided in the adjacent radiator.

The union of the Various radiators is effected, in an entirely traditional manner, by the engagement of externally threaded nipples in threaded portions 20 internally provided in the ends of said tubular member 18.

The working of the convector-radiator according to the invention, which is preferably produced in aluminium or aluminium alloy by means of diecasting and has all its corners rounded, is extremely simple. The water circulating in the tubular member 18 transmits its heat, through the low thermic resistance connection formed by the assembly of the baies 14, to the surface of the cover 3 and in particular to the front wall 6 which forms the radiating part of the convector-radiator. At the same time the bafe assembly forms a wide heating surface for air which enters the lower aperture 9 and exits from the upper aperture 10 and which expands, due to the defiectional action of the lid 7, in the surrounding atmosphere.

In practice all the materials and dimensions may be varied according to the requirements of use.
